What is the main benefit of using a heavier rear sway bar like this RockJock Antirock kit?

A heavier rear sway bar increases the rate of suspension resistance, which helps to better distribute weight and traction across all four tires. This is particularly beneficial when your Jeep is carrying extra gear or during aggressive off-road driving, leading to improved stability and traction.

Does this kit include everything needed for installation?

Yes, the RockJock Antirock sway bar kit includes all necessary components for installation. This includes the sway bar, frame brackets, bushings, forged arms, adjustable links, hardware, and step-by-step instructions.

Do I need to disconnect this sway bar for off-road use?

No, one of the key advantages of the RockJock Antirock sway bar system is that it is designed to remain connected and functional during off-road use, providing balanced suspension performance without requiring manual disconnection.

Product Details

The RockJock Antirock sway bar kit for the rear of your 2018-2025 Jeep Wrangler is built with a substantial 1 1/8-inch diameter, 28-spline bar. This heavier bar is specifically designed to increase the rate of your rear sway bar, making it ideal for Jeeps carrying extra weight like roof top tents, camping gear, or racks, and it's also well-suited for desert racing applications. When paired with a front Antirock kit, it helps balance front and rear suspension performance for better traction and weight distribution over all four tires in rugged off-road conditions.

Constructed from SAE 4130 heat-treated steel, the same material used in professional off-road competition sway bars, this kit offers ultimate strength. The kit comes complete with everything you need for installation: the heavy sway bar itself, semi-gloss black powder-coated bolt-on steel frame brackets, Delrin frame bushings, forged 4140 chromoly arms, adjustable length heim jointed sway bar links, all necessary hardware, and step-by-step instructions. This Antirock sway bar mounts into the frame crossmember in front of the axle and connects to the stock mounts on your axle housing. A notable benefit is that the RockJock Antirock sway bar does not need to be disconnected for off-road use, offering continuous support.
